I'm glad I didn't jump the gun and order the Garmin - I was *so* tempted (I posted recently about what kind of bike gadgets are good for altitude). Hmmm....choices seem to be wait for Garmin to fix the bugs (though I worry a bit amout the battery life - *if* I get into the more "epic" rides eventually - I think it's only 10 hours).
I'm leaning towards the Polar 720i since it's the only one I haven't heard complaints about. Hmmm....decisions, decisions....
No matter what, I'm leaving my basic specialized wireless computer on the bike - it works great and was very inexpensive. Has distance, current speed, average speed and time. Just about all I really *need* 
By the way, I have to second the comment on REI's return policy. They are GREAT! Hadn't heard that amount Nordstrom - good to know (though I'm a bit peeved at them right now - went clothes shopping for the new job and they told me my eyebrows looked terrible and I had to have them waxed. No thanks!).
Most days in life don't stand out, But life's about those days that will...
